lowing to be a full, clear, and eXact descrip-V tion of the invention, such aswill enable others skilled in the art to which it vappertains to make and use the same.

This invention relates to new andl useful improvements in blind fasteners and more f particularly to a device for holding blinds open or closed.

'Ihe particular object of the invention is to provide an improved fastener which can be used in connection with ordinary commercial staples, the latter being carried by the house wall and sill respectively for cooperation with the improved fastener to hold a blind open orclosed.

With the aboveand other objects in View, the invention resides more particularly in the peculiar combinations and arrangements of parts as will be partly illustrated as a preferred embodiment inthe accompanying drawings and described in the specification, although the invention' is protected for all desirable changes and uses within the scope of the invention as claimed.

Figure 1 is a vertical sectional view of a blind and portion of a sill with the vimproved fastener holding the blind in its closed position. Fig. 2 is an end view of a portion of the blind and an adjacent portion of the house wall with the fastener in use for holding the blind in its open position. Fig. 3 is a detail perspective view of a fastener. Fig. 4 is a horizontal sectional view of a blind and an adjacent wall portion and alsoy a fragmentary portion of .a sill, the blind carrying the fastener, and the wall and sills the staples which are adapted to coperate with the fastener.

In illustrating the preferred embodiment of the invention, there is shown a sill 10 of a frame 11 against which the blind 12 abuts. The blind is hinged in the usual manner as shown at 13 to the window frame and when open, extends over the adjacent portion of the wall 14 of the house.

The fastener embodies a single strip of metal indicated by the numeral 15, the same being apertured as shown at 1G for attachment to the lower edge of the blind transversely of the latter, so that the ends of the fastener project beyond the faces of the blind. The ends of the strips are bent inwardly to form tapered cam surfaces 17 and upwardly bowed portions 18, to provide grooves or keeper elements, and the inner ends or extremities of the strips are bent downwardly as shown at 19 to provide vertical flanges limiting shoulders.

In the operation of the device, the fastener is secured to the lower edge of the blind with they grooves 18 directed downwardly, and a staple 2O is driven into the sill for each blind, whereby, when the same is closed, the staple will pass over the tapered engaging portion 17 andbe thereby guided intoa groove 18. The portions 19 prevent movement of the staples beyond the eX- tremities of the fastener. When it is desired to hold the blind in an open position, a staple 21 is driven into the wall .of the house and the bight portion of the staple preferably bent upwardly as shown at 22 to similarly engage with one of the grooves 18 when the blind is open.

I claim: v

A. blind fastener for engagement at either end with a staple consisting of a spring metal plate having each end bent divergingly backward so that said ends are in spaced relation to its body portion, each eXtreme end portion of the plate extending at right angles away from the body portion to form a stop, and the plate being bent curvingly toward the body portion at each end adjacent to said right angularly extending portions so as to form a staple receiving groove, the plate in its body portion being adapted to receive securing means.

In testimony whereof, I aflix my signature, 1n the presence of two witnesses.
